Write protect mode

Changes can be prevented to the transmitter configuration data with the write protection electronics dip
switch 1. If the transmitter write protection is activated the transmitter will not accept any writes to its
memory. Configuration changes, such as trim and reranging cannot take place. In case the Digital LCD
Integral Display is installed the Write protect mode can also be set by HART command using the HHT and
the PC. Please refer to the device manual and Software instruction for the right operation.

Change the failsafe direction

The transmitter alarm direction is set selecting the Failure Mode in the transmitter software. The output value
is in accordance with NE43 NAMUR recommendations.
Navigate the Digital LCD Integral Display menu, select
the Failure Mode in use will be visible. To modify select
following table) with the up and down keys and confirm with OK.
As per Dip-Switch

Fail Low
Digital LCD Integral Display Keys sequence to change the failsafe direction: 2 – 4 – 1 - Edit

Set the Current Output limits

When the Current Output limits on alarm and saturation different from the selected is needed it is possible to
change it following one of the methods described in the next paragraphs.

Set the Current Output limits on the Digital LCD Integral Display

To set High Saturation current
Navigate the Digital LCD Integral Display menu, select
High Saturation > Edit, and the value change will be possible. Select the desired value and confirm.
Digital LCD Integral Display Keys sequence to set the High saturation current: 2 – 4 – 2 – 1 – Edit
To set Low Saturation current
Navigate the Digital LCD Integral Display menu, select
Low Saturation> Edit, and the value change will be possible. Select the desired value and confirm.
Digital LCD Integral Display Keys sequence to set the Low saturation current: 2 – 4 – 2 – 2 – Edit
To set Fail High current
Navigate the Digital LCD Integral Display menu, select
Fail High> Edit, and the value change will be possible. Select the desired value and confirm.
Digital LCD Integral Display Keys sequence to set the Fail High current: 2 – 4 – 2 – 3 - Edit
